Specification of Letters Patent.

Patented Oct. 26, 1920.

Application filed May 7, 1919. SerialNo. 295,307.

T 0 all whom it may concern:

Be it known that I, EUGENE O. FRITCH,

a citizen of the United States, residing 'at Schenectady, in the countyof Schenectady and State of New York, have invented certain new anduseful Improvements in Drill- Stands, of which the following is aspecification.

This invention relates to drill stands, and an object of the inventionis to provide a stand for drill bits, provided with a plurality ofsockets of various sizes to permit the supporting of various sized drillbits, and an object of the invention is to provide a drill stand, asspecified, which comprises a plurality of hinged connected sections,

' folded or collapsed each formed of pressed or cut metalfshaped toprovide a receiving portion for the shanks of the drill, to support thedrills in vertical positions, and also to provide detachable catchmembers for supporting and retaining the hingedly connected sections intheir extended positions. to support the drill stands against fallingmovement caused by the overtopping weight of the projecting portions ofthe drill bit, which fastening means are detachable to permit thesections of the drill stands to be folded into a comparatively compactspace. I

A further object of the invention is to provide a drill stand asspecified, in which the sections are substantially U-shaped in crosssection, having supporting plates attached thereto and positioned,intermediate of their ends, against which the lower or inner ends of theshanks of the drill bits engage, to provide corrugated plates within,the U-shaped body into the corrugations of which the shanks of thedrill bit are forced and retained by spring tongues cut from the sidesof the sections of the stand;

Other objects of the invention will appear inthe following detaileddescription, taken in connection with the accompanying draw ings,forming a part of this specification, and in which drawings:

Figure 1 is a top plan of the improved drill stand. showing it in anextended position.

Fig. 2 is a top plan of the drill stand in a 1position.

\ Fig. 3 is a vertica section through one of the sections of the drillstand, showing the drill in place therein.

Fig. 4 is a fragmentary longitudinal section through one of the drillstands;

Fig. 5 is a fragmentary horizontal section through one of the sectionsof the drill stand. 1

Fig. 6 is a fragmentary perspective view illustrating the manner ofbracing the hinged connection between the adjacent ends of two sectionsof the drill stand.

Fig. 7 is a fragmentary perspective illustratihg the mannerof hingedlyconnecting two adjacent ends of other sections of the drillstandstructure.

Fig. 8 is a fragmentary perspective illustrati'ng'the mannerofconnecting the free ends of the sections of the drill stand, and

Fig. 9 is a fragmentary vertical section through a modified form of oneof'the sections of the drill stand.

Referring more particularly to the drawings, 11 designates the drillstand as an entirety which is composed of a plurality of hingedlyconnected sections, illustrated in the drawin s as three, namely the sections 12, 1s and 14.

The bodies of each of the sections 12, 13 and 14 are preferably formedof sheet metal, and bent to assume substantially an inverted U-shape asclearly shown in Fig. 3 of the drawings, having their upper horizontal Iportions 25 provided with a-plurality of openings 26, varying in sizeand adapted to receive drill bits of various sizes. The openingspreferably are graduated, from the larger size drill to be supported tothe smallest, as clearly shown in Figs. 1 and 2. The drills, asindicated at A in Fig. 3 of the drawings, are inserted through theopenings 26 and their lower ends rest upon supports 27 These supportsare preferably made separate from the body of the sections and areretained in proper position by tongues 28 which extend through suitableopenings in the depending sides 29 of the supports 27. The tongues 28are punched from the parallel sides of the inverted U-shaped bodies ofthe sections as clearlyshown in Fig. 3 of the drawings. Plates 30 areplaced upon the supports 27 adjacent the outer sides of the sections,and these plates are provided with .depends' or outstruck portions 31,the concave surfaces of which face toward the sides 9 of the sections,formin partial pockets for receiving the shanks o the bits A as clearlyshown in Fig. 5 of the drawings. Spring tongues 32 are cut from theinner sides 901: the sections and these tongues are curved inwardly andslightly outwardly as shown at 33 to provide spring contact with theshanks of the bit inserted through the openings 26 to force the shanksinto the concave portion of the plates 30 for securely supporting thedrills in the stand structure 1 and to prevent the drills from fallingout of the drill stand when the latter is turned upside down or placedupon its side.

The plate 27 of the various sections 12, 13 and 14 have cars 36 formedupon their end portions to which ears the links, which hingedly connectthe various sections, are con nected.

For instance, the plate 27 of the section 12 of the drill stand has alink 38 pivotally connected thereto by means of a suitable pin 39. Thislink 38 is also connected to the ear 36 carried at the end of thesection 13 adjacent to the end of the section 12 to which the link 38 ispivoted. The link 38 is also pivoted to the car 36 of the section 13 bya pin 40. The link 38 has extensions 41 formed upon its ends, whichengage the ends of the outer sidesof the sections 12 and 13, as clearlyshown in Fig. 6 of the drawings to limit the relative movement of thesesections.

The adjacent ends of the sections 13 and 14 are hingedly connected by alink 42, which is pivotally connected by means of pins 43 to theprojecting ears 36 which are formed upon the ends of the plates 27carried by the respective sections. The link 42 is provided with acut-out portion 44 in one edge thereof which receives therein, the endportions of the sections 13 and 14 when in an unfolded or extendedposition as shown in Fig. 1 of the drawings, the shoulders formed in theends of said cut-out port on engaging the inner surfaces of the innerside of the section and limiting their pivotal movement toward eachother.

The ends of the sections 12 and 14 remote from the edge thereof to whichthe links 38 and 42 respectively are connected, have looking links 45and 46 pivotally connected thereto. The link 45 is pivotally connectedby means of a pin 47 to the ear 36 and rests upon the upper surface ofthe same, while the link 46 is connected by means of a pin 48 to the car36 which projects from the end of the plate 27 carried by the section12, and beneath these ears as clearly shown in Fig. 8 of the drawings.These pivoted locking links 45 and 46 are provided with notches 49 ineach of their side edges near their free ends. When the sections are inan extended or unfolded position, as shown in Fig. 1 of the drawings,the adjacent ends of the sections 12 and 14 are connected, by theinterlocking engagement of the links 45 and 46 with the projecting endsof the pins 47 and 48, the said pins projecting upon the opposite sidesof the ears 36, from the sides upon which carries the same, as clearlyshown in Fig. 6 of the drawings, so that when the sections 12, 13 and 14are folded, as shown in Fig. 2 of the drawings, the notch or recess inone edge of the link 45 engages the'upper projecting end of said pin,while one of the notches 49 of the link 46 engages the end of the pin43, thereby locking the various sections 12, 13 and 14 in their foldedpositions.

In Fig. 9 of the drawings, a modified form of the stand is shown. Inthis construction, the upper horizontal portion 25 of the sections ofwhich the drill stand 1 is formed,

are provided with openings 26 adapted to' receive the shank of a drillbit B therethrough, and the support 27 which is supported between theparallel sides 9 and 10 include substantially parallel horizontalportions 30 and 31 positioned in superposed relation. The upperhorizontal portion 30 is provided with openings 32 alining with theopenings 26 and adapted to permit the inner or lower ends of the shankof the drill B to extend therethrough for resting upon the lowerhorizontal section 31 This support 27 is attached to the sides 9 and 10by tongues 28 which extend through suitable openings in the verticalportions of the supports 27*. Plates 33 which are provided with suitabledepressions similar to the plate 30 are provided in the modifiedconstruction of the drill stand, into which pockets or outstruckportions the shank of the drills are forced by spring tongues 34 whichare cut from the sides 9 of the sections of the modified form of thedrill stand.

The plates 30 and 33 are maintained in their proper positions by meansof upwardly and downwardly extending tongues 35 which extend throughsuitable openings in the horizontal portion 25 of the sections and thehorizontal portions of the support 27 as clearly shown in F ig. 4 of thedrawings.
